Hello, I meet this case, i don't have file Laptop

[Dandeptraibodoiwa]

i don't have file laptop in this case
" cp /mnt/etc/nixos/hardware-configuration.nix /mnt/etc/nixos/Flakes/hosts/laptop/hardware-configuration.nix "
i have been create file laptop and " cp /mnt/etc/nixos/hardware-configuration.nix to laptop "

I'm quite confused when using this command and did it like this
_**{ inputs
, sharedModules
, homeImports
, user
, ...
}: {
flake.nixosConfigurations =
let
inherit (inputs.nixpkgs.lib) nixosSystem;
in
{
k-on = nixosSystem {
specialArgs = { inherit user; };
modules =
[
./k-on
../modules/lanzaboote.nix
# ../modules/impermanence.nix
../modules/desktop.nix
../modules/fonts.nix
../modules/virtualisation
{ home-manager.users.${user}.imports = homeImports."${user}@K-ON"; }
]
++ sharedModules;
};
minimal = nixosSystem {
specialArgs = { inherit user; };
modules =
[
./minimal
../modules/impermanence.nix
../modules/systemdboot.nix
../modules/impermanence.nix

      ] ++ sharedModules;
  };

#};
}**_

i have access into this file
"8. Username modification: edit /mnt/etc/nixos/Flakes/flake.nix to modify user variable, hostname modification: edit /mnt/etc/nixos/Flakes/hosts/system.nix to modify* The hostName value in the networking property group"
"9. Use the hash password generated by the mkpasswd {PASSWORD} -m sha-512 command to replace the value of users.users..hashedPassword in /mnt/etc/nixos/Flakes/hosts/laptop/wayland/default.nix ( there is two place needs to be displace ) "
but it empty, should i skip this step.

I have been install " nixos-install --no-root-passwd --flake .#laptop " then reboot but It is still a minimal console and and requires login. I don't know what to enter into it.

Can i install it after installing nixos minial ?
Sorry if I bother you. Looking forward to your and everyone's help.
